I always hesitate to characterize these people whom we don't really know. For example, Kyke Okposo Good Man. Who knows?
We can only go by what we know. Terry might not be mean, but on Day One he went to visit TBN and he went after them. I might never forget how he sat there and scraped the junk out of his fingernails onto the conference room table. Yes, it happened!
I think there's a passive aggressiveness to the man. Mean? How about ghosting Sabres fans? Cruel, at the least. And that's not to mention what he's actually done to come close to destroying the franchise.
I've always suspected that a change took place when he was booed on RJ Night.
